Tab-Canvases and F2
I just found an interesting undocumented feature:
While the cursor is inside a tab-canvas you can press F2
Then you see a little list-item in the upper-right corner of the tab-canvas. There you can move up, down and press Enter or Return.
This starts the WHEN-TAB-PAGE-CHANGED-trigger. Here you can do whatever you want. For example a navigation to a block and starting a query.
Have fun
